Samsung new 9 series is the lightest and ultra-slim notebook in the world... You can claim the Vat Back (Save £199.83 redemption on-line), plus free Microsoft mouse and get 3 year guarantee (normally one year).

The dell XPS is hardly a ultra-book is it... so not exactly an option for someone looking for a ultra portable thin laptop...

The New XPS 13 from Dell that is £949 with the i5 processor and 128gb SSD is a much better option to compare the price against... and that £949 is before you take off any discount voucher or Quidco.. should be able to pick one up for about £850
